When I first saw this rifle I called and asked the gunshop was the 7mm Special a Newton Special? I did so because he has in his ad 7x57 after the words 7mm Special. They explained to me a 7mm Special was "just" a 7x57 with a different twist rate than a normal 7mm Mauser [7x57]. I said I had never heard of this derivation and was told the gunsmith had done a chamber cast!!!!! He also allegedly fired several rounds of 7x57 without a change in the brass and with no problems!!! I for one don't think I have ever heard anything like this in my 50 years in the business. THE RIGHT HONORABLE Mr. Behrman... WHAT SAY YOU? Warmest Regards
